Women who experience urinary urgency need to go to the hospital for further examination to clarify the possible causes. Common causes are: 1. When urinary tract infection occurs, there can be obvious urinary urgency, accompanied by urinary frequency and painful urination. It is common in acute urethritis or acute cystitis when the infection or local mucous membrane edema produces a strong irritation and produces urinary urgency. Routine urine laboratory tests are needed to clarify the infection and then anti-infection treatment.2. If there are bladder stones or stones in the lower ureter, etc., strong urinary urgency can also be produced. The stones act as an irritant, causing the patient to produce the will to urinate at all times, while mostly accompanied by pain in the lower abdomen, or pain on the pubic bone, and also accompanied by symptoms of hematuria in the naked eye. Ultrasound examination of the urinary system is required to determine the presence of stones and extracorporeal shock wave lithotripsy is required. 3. Overactive bladder syndrome. When infection or stones and other lesions are ruled out, it may be due to excessive contraction of the bladder forcing muscles, resulting in symptoms such as frequent urination. Routine tests such as urinary routine, or urological ultrasound are normal, but further urodynamic tests are needed to confirm the presence of excessive, frequent or uncontrollable contractions of the bladder muscles, which can be diagnosed as overactive bladder.
